Reproduction in an isolated test environment confirms the failure sequence:
When any generator hits the 90s timeout during daemon-reexec, the resulting -EPROTO causes manager_startup() to abort, and PID 1 enters fatal freeze_or_exit_or_reboot(). An upstream pull request has been submitted to address both the core resilience and the network mount chasing: https://github.com/systemd/systemd/pull/44369 1. core/manager: during daemon-reexec (serialization != NULL), generator failures are logged as warnings and do not abort manager_startup(), matching daemon-reload resilience. 2. fstab-generator: skip chase() for network mounts (mount_is_network()), using path_simplify() to avoid blocking in D-state. ** Changed in: systemd (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2165295 Title: systemd freezes after daemon-reexec triggered by unattended-upgrades / needrestart on Ubuntu 24.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2165295/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
